Abstract:

The paper presents the experimental study of the surface profile of a thin horizontal liquid layer. Surface deformation is caused by thermocapillary convection due to local heating of liquid. The measurement of the local layer thickness was carried out using photoabsorbtion. Video of the process allows to track the dynamics of the profile over time. The surface profiles were obtained for the layer of brilliant green solution in isopropanol at different times from the beginning of the heating.
